The gaming industries sales were down significantly this year versus last year. Expectations are usually the sales will exceed the previous year. It's obviously down because last year saw the Kinect and Playstation Move launches. This year we had only the Nintendo 3DS which many (not me) believe launched over priced and then had some key titles post-poned until more consoles were in consumers hands.
I think the Kinect and Move failed to give us anything to buy over the holiday season and developers are holding back some content for the next gen; espeacially if games will be Wii-U portable as well.
